Subaru-led team discovers a rare stellar disk of quartz dust
Collisions of planetesimals, building blocks for planets, may have produced the dusty quartz ring during planet formation around the star.
A research team of Japanese astronomers led by Hideaki Fujiwara from the Subaru Telescope has discovered a main sequence star that is surrounded by a rare disk of quartz dust. Collisions of planetesimals, building blocks for planets, may have produced the dusty quartz ring during planet formation around the star. Based on observations with the AKARI and Spitzer infrared space telescopes, this recently discovered intriguing feature of a stellar system may open new doors for research on the mineralogical nature of extrasolar planetary systems.
